VHF Fixed Stations

Quickly transmit a distress signal to nearby vessels with the emergency button, which uses Class D DSC to automatically send crucial information that can help emergency services. You can also use the intuitive DSC functions to quickly contact other AIS-equipped vessels: simply select the vessel in the AIS plotter view and call it by touching a button.

• Stay alert on the water with built-in AIS transmitter and receiver functions. This feature shows you the scale, route, speed, and crossing situation of other AIS-equipped vessels around you to help you navigate.
• Eliminate unnecessary radio noise with the automatic squelch. If you miss a radio message, you can replay it with VHF audio playback. When you need to monitor multiple channels, the advanced monitoring modes make the task easier.
• Configure the radio, program the MMSI number, and receive wireless software updates with the <a href='https://www.garmin.com/en-US/p/573254/'>ActiveCaptain™ smartphone app</a> via built-in Wi‑Fi^® connectivity.
• Installation is simple, as the VHF/DSC/AIS functions require only a single VHF antenna, and the GPS antenna/receiver is integrated into the head unit. Integration with plotters is easy via the NMEA 2000^® and Garmin BlueNet™ Network.
• All VHF channels are continuously scanned for background activity, allowing you to simultaneously monitor channel 16 and all your favorite default channels.
